ELECTRIC LAMP SOCKET.

APPLICATION FILED 00T. 14, 1907.

i the circuit just broken.

switch the spindleis held against a returnl revolution.

In connection with the spring 31, I provide an adjusting device 33 which com- `prises a sleeve be'aring for the spindle' 22,

aving an angled portion 37 to correspond to the angled hole39 in the ystandardjf24= in which it 1s supported, and a shoulder 38 to prevent said sleeve from being ,pushed throughthe hole 39 by the spring. To tension the spring the adjusting device is pushed in until the angled part 37 is clear of the hole 39. The sleeve may then be freely rotated. After the desired tension for the spring has been attained, the sleeve is drawn out or forced/ out by the spring until the part 37 engages in the hole 39 and is thereby held againsty rotation, while the spindle22 is free to rotate in the sleeve as may be necessary for the operation of the switch. j

The construction may be varied in detail from that illustrated and described, without avoiding my invention.

I claim as my invention:

1. In a pull socket for an electric lamp, an insulatlng base recessed .to form two chambers, a switch spindle extending throutgh both of said chambers, standards in one o said chambers supporting said spindle and a ratchet mechanism for operating said spindle located between said standards, in

combination with a circuit terminal located in the other chamber and a contact member on the switch spindle adapted to establish the circuit between said circuit terminal and alam terminal.

2. IIii a pull socket for an electric lamp, an insulatlng base recessed to form two chambers, a switch spindleextending through both of said chambers, standards 1n one of said chambers supporting said spindle and which said arms impinge to prevent the ro.

tation of the spindle in one direction.

3. In a pull socket'for an electric lamp, aninsulating base recessed to form" two chambers, a switch spindle extending through both of said chambers, standards in one of said chambers supporting said spindle and a ratchet mechanism for operating said.

spindle located between said standards, in

` combinationwith a circuit terminal located inthe other chamber, a screw shell above said terminal and a contact member-on the switch spindle adapted to establish the circuit between said circuit terminal and shell, the latter beingoifset to insure a better contact with said switch member and to facilitate the assembly of the shell and base, as described.

4. In a pull socket for an electric lamp, having lamp and'circuit terminals, a' circuit closer operating between a lamp and a circuit terminal, a spindle carrying the same, standards supporting said spindle, a spring actuated ratchet device to actuate said spin'- the spring of said ratchet device, said means comprising a -sleeve to which one end of the spring isr'secured and forming a bearing for said spindle and comprising a hollow shank a retaining flange thereon and an angled portion adjacent thereto, said retaining flange being adapted to be pressed against the side of one of said spindle standards by the spring and said irregular portion being j aperture 1n said standard, the shank affording means for disengaging said sleeve from the standard, and guiding the, same in said aperture during its rotation for the purpose o adjusting the tension of the spring.

In testimony whereof I have signed my name to this specification, in the presence 0f two subscribing witnesses.
